Fast and Accurate ESMA reporting

A global move towards digital clarity

ESMA’s latest mandate, the European Single Electronic Format (ESEF), requires all EEA-based ‘main market listed companies to digitally tag their annual financial reports. ESMA aim to improve analysis and comparability for financial statements and to make information more accessible for businesses and auditors alike. 

The electronic format for ESEF is an iXBRL tagged xHTML file, which is different from the current PDF ‘glossy’ formatAt Arkk, we have ten years’ experience supporting hundreds of clients in the UK and Ireland with their iXBRL returns. This year, we’re applying that knowledge to ESEF.  

Your ESEF requirements made simple

Our experts will tag, review and return your annual reports, ready for the publication. We’ll provide: 

  • The final xHTML file 
  • A report of all tags applied 
  • A report of all anchored tags  

We’re working closely with clients on a pilot basis in 2019, through to the first live filing in 2021, ensuring that tagging is swift and successful first time.  

Design Agencies and Individuals; a solution for all

Whether you’re producing financial statements on behalf of your clients or managing your end of year reporting in-house, Arkk provides accurate, timely tagging to get your documents ready for ESEF compliance.  

High calibre UK-based support, tagging from iXBRL experts and a robust review process for every single document. Whatever your requirements, we’ll take the hassle out of ESEF reporting.

Key Features

  • Tagging Guaranteed
    Last year, our tagging team in Belfast applied more than 1,000,000 tags to over 4,500 documents, all of which were returned to our clients on time and ready for their filing deadline. This includes a tagging report explaining why tags are chosen, and the opportunity to review returns.
  • In some instances, ESEF filings will need tagging within 24 hours. That’s why the Arkk process will have your draft statements “pre-tagged” to ensure that the final version can be tagged, checked and returned within one day.
  • Experts in iXBRL
    The chosen format for ESEF filing is iXBRL, which is embedded in an xHTML document. At Arkk, we’ve supported firms with their iXBRL reporting requirements for ten years and are recognised by HMRC as a vendor.
  • Quality from start to finish
    We believe that expert tagging goes beyond the publication. Our dedicated account management and support teams are available for taxonomy guidance, technical support, and to discuss tagging options under the ESEF ‘anchoring’ method.
